Answer:

because the soap is a base

Explanation:

as we know that turmeric is a natural indicator, it turns red when it comes in contact with a base.

soap or any detergents are bases, so when the turmeric stain is washed with a soap (base) it turns red.

Answer:

Turmeric is a natural indicator which turns red in the presence of base and doesn't change colour for acids i.e. stays yellow. As soap is a basic substance, so when we wash clothes with soap having turmeric stains, the turmeric turns red.

Indicators are the substances which indicates the presence of acids or bases by showing changes in their colour. Indicators are of two types: Natural indicators and synthetic indicators. Litmus, China rose, red cabbage are some more examples of natural indicators. Methyl orange and phenolphthalein are examples of artificial indicators.
